EPA and Respondent entered into a settlement agreement and order on consent (RDAOC) for the design of the selected remedy at Operable Unit 4 of the Olean Well Field Superfund Site. In addition to the performance of the remedial design, valued to be approximately $500,000, the Respondent will pay $800,000 of EPA's past response costs related to OU4, and all of EPA's future response costs for overseeing the work required under the settlement agreement. In exchange, the Respondent will receive a covenant not to sue for the work required to be performed and for the costs paid, subject to a reservation for future work to be performed at OU4 at the Site as well as for other operable units at the Site, and for the remainder of EPA's past costs associated with OU4.
